My ABS light will not go off. The brakes are working fine. Occasionally the tripmeter will stop but speedometer works. I have been told that the metering block needs to be replaced but, I cant get any information on this part. Its not the correct name for it. Can you tell me if I am on the right track with this and what is the correct name for the part that I need?
